UPS Drivers to Use New Wireless Computers

UPS recently unveiled a new generation of wireless hand-held computers to be used by its drivers. The fourth generation Delivery Information Acquisition Device or DIAD IV, incorporates new communications links, expanded memory, and a color screen that allows alert messages to be color-coded for drivers.

Each DIAD IV will feature a built-in Global Packet Radio Service or Code Division Multiple Access radio (depending on the area of the world in which it is operating); an acoustical modem for dial-up access if necessary, and wireless local area network connectivity (Wi-Fi) to enable transmission within a UPS center. The device also features a Bluetooth wireless personal area network and an infrared port to communicate with peripheral devices and customer personal computers. The DIAD IV enables drivers to confirm deliveries almost instantaneously. Drivers simply scan the package bar code; collect the receiver's signature electronically; type in the last name of the receiver, and push a single key to complete the transaction and distribute the data. There is no need to activate a cell phone or return to the vehicle to place the device in a transmission cradle. Developed in conjunction with Symbol Technologies, UPS will begin deploying the DIAD IV in 2004 after completing extensive tests of the new device later this year.

MobileInfo Comments and Advisory: UPS is a leader in exploiting wireless for its core business operations. It is large and it has a lot of experience in doing it well. Therefore, it is noteworthy to observe that it decided to have a combination of network adapters - GPRS, CDMA, Wi-Fi and good old dial-up as a backup. Large enterprises and vendors could learn from UPS. Sooner we start understanding the realities of wireless network LANdscape, better we might be in building hybrid networks and devices with support for multiple networks. For sometime, It aint going to be a single wireless network that will provide universal coverage.
